    • ...A number of authors [Baker et al., 1992; Komatsu et al., 1992; Kargel et al., 1994; Bussey et al., 1995; Williams-Jones et al., 1998; Bray et al., 2007] have suggested that the canali-type channels result from low-viscosity carbonatite or sulfur magmas...
    • ...Baltis Vallis, the longest known channel in the solar system, has mappable segments totaling around 7000 km in length [Baker et al., 1992, 1997; Komatsu et al., 1993; Bray et al., 2007]...
    • ...The Venusian canali used in this study (data from Bray et al. [2007]) have average widths and rates of change in width shown in Figure 2. Figure 2 also shows statistics for the Amazon and Zaire submarine channels (data from Pirmez and Imran [2003] and Babonneau et al. [2002], respectively) and for several sinuous rilles on Venus and the Moon (including ‘‘RH1’’ taken from Greeley and Spudis [1978])...
    • ...2.3. Channel Topographic Profiles [13] Figure 6 shows the along-channel altitude variations for the Amazon channel, the canali shown in Figure 4, and Figure 2. Rate of width change as a function of average width for Venusian canali [from Bray et al., 2007] and for the most distal 450 km of the Amazon [Pirmez and Imran, 2003] and Zaire [Babonneau et al., 2002] submarine channels on Earth...
    • ...[14] The relationships between meander wavelength and the radius of curvature of canali-type and other solar system channels are discussed by Baker et al. [1992], Komatsu and Baker [1994], Jones and Pickering [2003], and Bray et al. [2007]...
    • ...When graphically comparing these dimensions, trend lines of volcanic channels tend to be steeper than those cut by aqueous fluids [e.g., Baker et al., 1992; Bray et al., 2007]...
    • ...These values are far shallower than the trend lines for Venusian channels of confirmed volcanic origin (gradient of 0.74 ± 0.11 [Bray et al., 2007])...
    • ...Bray et al. [2007] report trends similar to those of the volcanic channels for sinuous rilles from Venus (0.70 ± 0.25) and the Moon (0.72 ± 0.04)...
